Description

Wooden tray rapid pest-removing treatment system
Technical Field
The invention relates to the technical field of pest elimination of wooden products, in particular to a quick pest elimination treatment system for a wooden tray.
Background
According to the regulations of the international plant product protection convention, wooden packages used for outbound goods must be subjected to pest control treatment. At present, the wood package harm-removing treatment method adopted internationally mainly comprises three methods:
(1) Fumigating treatment (MB) with medicine. The method begins with placing wooden pallets into an enclosed space (wooden bags are typically covered with tarpaulins)Covering well), then adding methyl bromide or other chemicals into the tarpaulin, and carrying out fumigation and pest-removing treatment on the wooden package in the tarpaulin at the treatment temperature of not less than 10 ℃ for not less than 16 hours[1]. The method has good harm-removing effect and convenient and flexible operation, but because the methyl bromide has certain toxicity and long harm-removing treatment time, the method is applied less and less at present.
(2) Heat Treatment (HT for short). The method also comprises placing the wooden tray into a closed space (usually a heat treatment kiln), introducing hot air steam into the heat treatment kiln to heat the wooden package in the kiln, continuously raising the temperature of the wooden core, and finishing the heat treatment harm-removing process when the temperature of the wooden core is raised to above 56 deg.C and kept for above 30 min[1]. The treatment method has the characteristics of good harm-removing effect, environmental friendliness and the like, is a wood package harm-removing treatment method widely used at present, but has long treatment time and certain limitation on productivity.
(3) Dielectric Heating (DH). The method is a new wood harm-removing treatment method in recent years. The method comprises the steps of putting wood into a treatment cabin, and then heating and detoxifying the wood by using high-energy microwaves. The treatment method has the advantages of high pest-removing treatment speed and low energy consumption, and is the development direction of pest-removing treatment of the wooden package in the future. However, since the dielectric heating treatment method requires strict control of the temperature of the wood core of the wood, if the temperature is too low and the duration is too short, the effect of the pest-removing treatment is not good, and living insects and ova remaining in the wood cannot be completely killed; if the temperature is too high and the duration is too long, the phenomenon of yellowing and even carbonization and blackening of the interior of the wood can occur[2]It is very easy to cause fire and causes serious consequences.
In view of this, it is necessary to propose a complete pest elimination solution for the above-mentioned method 3.
